Intro Flashcards
Assumption
This philosophy guides our practices – without a belief in this philosophy, there would not be a point to our practices
Determinism
Human behaviour obeys the laws of nature
Behaviour acts as other natural events do
All events are related to other events in the past
Subject to scientific exploration and investigation
Determinism
There is order in the universe
Order allows scientific exploration
Scientific inquiry comes from…
The opposite of accidentalism
Determinism
One event is caused by another
Links in a chain
Determinism
Things do not happen by chance
example: an explosion is caused by gas expanding and chemical mixing
Determinism
A prime directive
Empiricism
Observation, measurement, gathering objective facts
Empiricism
Relying on observable facts and not opinions
Direct observation and measurement
Empiricism
To understand something we must describe, predict, and control it
Empiricism
Free from bias
In the sense of saying something is or isn’t true based upon personal prejudice or opinion
Multiple people can observe the same event
Empiricism
Requires clear description of the phenomena so that observation can occur unbiased
Empiricism
Yields qualification of the results
Crosses over all 3 levels of scientific understanding: Description, Prediction, Control
Empiricism
A basic strategy
Experimentation
Conduct experiments, systematically measuring aspects of the phenomena of interest
Experimentation
Used to determine functional relations
Required in scientific inquiry
Systematic and controlled
Experimentation
Manipulate one (environmental) variable and keep other variables constant
Experimentation
What is manipulated in a scientific experiment; variables that are typically thought to have some effect on the dependent variable
Independent Variable
The measured variable; the variable that is affected/dependent upon the IV; not manipulated but observed
In behaviour analysis, this is usually the “behaviour”
Dependent Variable
A necessary requirement for believability
Replication
Not the infallibility or inherent honesty of scientists – is the primary reason science is a self-correcting enterprise that eventually gets it right
Replication
Repeating an experiment as many times as necessary to show same/similar results
Successful results of one experiment = great!
However, value is placed on repeated application yielding same results
Replication
Within one experiment (e.g. a design repeating each condition/intervention twice)
Across many experiments (e.g. across different participants, behaviours etc.)
Replication
Manipulation of variables
Experimentation
Change in one variable to see how it effects the other variable
Experimentation
How blood pressure (DV) changes due to the change of water intake (IV)
Experimentation
Being able to repeat something done once
Replication
Re-introduce variable / intervention to see effects on results across multiple experiments and people to have believability in hypothesis
Replication
Tanya recently began working with a client who is 3 years old. She saw in his file that he has had several different types of assessments conducted on his behavior in his short life. She reviewed the different assessments and came to the conclusion that his problem behaviors allow him to escape difficult demands. This is an example of experimentation
False. She only made a prediction, she did not control variables
Andre was examining the problem behavior of yelling for one of her clients. After clearly defining the behavior, she asked the staff at the group home to record when the behavior occurred based upon the definition of the behavior she provided (and trained) them. Which attitude of science did Andre adhere to?
Empiricism; objective observation and measurement of the phenomenon
A conservative value
Parsimony
Simple, logical explanations chosen over more complex or abstract
Parsimony
Frugality
Simple and logical (as compared to other explanations)
Requires the fewest assumptions
Occam’s Razor
Parsimony
We do not want to jump to complex assumptions without first ruling out simplest explanation
Parsimony
A guiding conscience
Philosophic Doubt
Healthy level of scepticism
Philosophic Doubt
Helps with process of being self correcting
Philosophic Doubt
